The present invention relates to improvements in combined refrigeratorsand ice cream freezers and has for its principal object to provide astructure that comprehends l the association of anice cream freezermechanism with a power operated refrigerator.

One of the important objects of the present invention is to provide astructure of the above mentioned character wherein the ice 1o: creamfreezer unit is removably positioned within one of the compartmentsprovided in the freezing chamber for the reception of the removable icepans or trays.

A further important object is to provide I 115 a device or structure ofthe above-mentioned character wherein the ice cream. freezer 1n-V cludesa stationary horizontally disposed cylinder within which is rotatablymounted y a stirrer, means being provided whereby theV vention is toprovide a combined refrigerator and ice cream freezer which will notnecessi- @il tate any material alterations ofthe refrigeraw tor toaccommodate the ice cream ,free-zer, said 1ce cream freezer beingreadily and easily inserted and removed from the refrigerator.

et A further object is to provide e structure of the above-mentionedcharacter whereby considerable time and labor will be saved in makingice cream and at the same timev utilizing the freezing chamber of therefrigerator to freeze the ice cream, it being only necessaryto ,removetwo of the ice pans vor trays and the supporting partition to permit thepositioning of the freezer unit in the chamber.

Other objects and advantages of the invention will become apparent fromthe following description when taken .in connection with theaccompanying drawings'. y

In the accompanying drawings wherein like reference characters indicatecorrespond- 45 ing parts throughout the same ;l

Figure l is a front elevation of anA electric household refrigeratorshowing the ice cream freezer'unit positioned in the freezing chamberand the motor for actuating the stirrer connected up therewith. l

Figure 2 is a sectional view taken approximately on the line 2-2 ofFigure 1 on an enlarged scale.

Figure 3 is a vertical section taken on line 3-3 of Figure 2, looking inthe direction of the arrows.

Figure 4 is a detail of the detachable connection between the drivenshaft and the drive shaft ofthe motor; and i l Figure 5 is a sectionalview taken approximately on the line 5-5 of Figure 2, looking in thedirection of the arrows.

ln the drawings wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral l designates generallythe cabinet of an -electric refrigerator, the freezing compartment'thereof being indicated at 2. The refrigerating mechanism which is of aconventional construction is not shown in the drawings as the same formsno important part of the present invention, the only part of therefrigerating mechanism that is necessary to be il` lustrated anddescribed are the coils 3 through which the refrigerant circulates.

y The coils 3 encircle the ice pan or tray receiving compartment 4: thatis open at its front side and a cover plate 5 is disposed over the openfront side of the compartment d and is secured to the verticalwall 6arranged in the chamber 2 by any appropriate fastening, means. loe traysupporting shelves 7 are arranged in verticallspaced relation within thecompartment 4 in the usual manner'and the removable ice pans or traysthat are positioned within the compartment 4 are shown at 8 in Figure 1.lt is of course understood.

that the plate 5 is provided with openings to accommodate the. removableice pans or trays 8.

The liquid refrigerant is supplied to a boiler or header ,not shownthrough the means of. a compressor and condenser operated by suitablepower means such as an electric motor all of which are well known in theart and are not shown and the liquid re' frigerant circulates throughthe coils whereby to freeze'the water placed in the pans or trays 8.This same mechanismmay be employed for freezing ice cream and toI thisend, certain of the ice pans or trays are removed and positioned inthecompartment 4 vacated by the aforesaid ice pans or trays is V .freezerunit is horizontally positioned and the closure 12 is formed with a boss14 that extends through a central opening formed in the closure plate 13as shown very clearly in Figure 2.

Journaled for rotationwithin the cylinder 11 is the stirrer shaft 15.The inner or rear endthereof is formed with a reduced portion 16 that isjournaled for .rotationfwlthin a suitable bearing 17 arran ed on theinner face of the closedend o the cylinder 11. The forward end of thisshaft 15 is journaled through the boss 14 and the forward extremity ofthisY shaft is substantially square in-cross section and of a suitablelength as indicated at 18 alsoA in Figure 2. A series of stirringelements or paddles 19 extend radially from the shaft 15 for'dispositionwithin the cylinder 11 for tlie purposes well known in the art.

The operating means for the rotatable stiri rer includes a beveled gear2li) that is removably'secured on the squared forward end 18 I of theshaft 15. A small electric.motor\21 of any conventional construction issupported on a suitable bracket 22 adjacent the front side of thepartition or wall 6 and the drive shaft 22 of this electric motor 21 isformed with a socket 23 that is open at one side as indicated at 24 inFigures 4 and 5 of t'he drawings. A beveled notch 25 is formed in theclosed end of the socket 23. g

Remoyablv secured within the socket 23 'is the inner end of a drivenshaft 2G,that carries at its outer end a beveled pinion 27 for meshinglengagement with the beveled ear '20. The inner end offthe shaft 26 isof t e same configuration as `the socket 23 and is formed at itsextremity with a nose portion 28 for .rect-ion of the arrow in Ficooperation with the beveled notch 25 as shown very clearly in' Figure4. Additional securin means for the driven` shaft includes a thum screw29 that extends transversel through the inner end portion of the sha t26 and the threaded' end of this screw is threaded through an openingformed in the closed side of lthe socket 23. By removing the thumb screw29 from the threaded opening 30, the shaft 26 may be swung in the dire-4 to facilitate its removal from the dr1ve'shaft-22- and when the partsare connected in the manner as shown and the inion 27 meshes with thebeveled gear, 20, w en the motor 21 is in o eration, the stirrer in\th ecylinder 11 will rotated to churn the ice cream and the re'- frigerantthat circulates through the coils 3 y,will freeze the ice creamin apositive and efficient manner and also .in a very short time. In lieu ofthe motor `operating means for the stirrer unit, a hand crank not shownmay be removably secured on the squared forward end 18 of the shaft 15so that the `stirrer will be operated manually.

After the ice cream has been manufactured rin its frozen state, theentire freezer unitmay be removed from the compartment 4 and the icetrays re-inserted therein and the water in the trays will be quickly andeasily frozen by 'the coils 3 in the manner well known in YIt will thusbe seen from the foregoing description, that I have provided a combinedrefrigerator and ice cream freezer that will save considerable expenseas well as time and labor in the makin Where domestic re igerators areused and furthermore the ice cream freezer is of such construction asnot to necessitate any material alterations of the refrigeratingapparatus when said lfreezer is brought into use.

While I have shown the preferred embodiment of my invention, it is to beunderstood that minor changes in the size, shape and arrangement ofparts may be resorted .to without vdeparting from the spirit of theinvention or the scope of the appended claims.

What I claim is 1. In combination with a domestic refrigerator-having afront door and an open front ice tray receiving chamber surroundedby ofice cream in homes refrigerating coils, a frame removably fitted in thelower portion of said chamber, an ice' cream freezer including ahorizontal cvlinder mounted in and carried by said frame for preventingthe freezer from contacting with the chamber walls, and a stirrer.mounted in said cylinder and provided with an operating shaft having aprojecting front end adapted to be engaged by an operating crank whenthe front door of the refrigerator is opened.

2. In-combination with a domestic refrigerator having a front door andano n front ice tray receiving chamber slrr'oun ed by remensa?frigerating coils, a frame removably fitted 1n the lower portion of saidchamber,.an ice cream freezer including a horizontal cylindermounted inand carried by said frame for preventin the freezer from contacting withthe cham r walls, and a, stirrer mounted in said cylinder and providedwith an op-l erating shaft having a projecting front end,
